Also, it is not 'best to avoid this function' as you state. What is best is follow Patrick's advice and just copy it directly into your own shell script.

So if your path contains: /bin:/usr/bin pathmunge /usr/bin will do nothing. pathmunge /sbin will result in a path a path containing: /sbin:/bin:/usr/bin if instead, you'd said pathmunge /sbin after, the result would have been: /bin:/usr/bin:/sbin For portability, if you need something like this, just make it a part of your script.
